On this date in 1945 the discovery of the element americium was announced. Here are 10 facts about the element.

Das ist Americium 241 ein Alphastrahler. (Alphastrahlung->Durch den Tunneleffekt aus dem Atomkern abgestrahlte Heliumkerne)
Durch den Rauch (bei einem Brand) erreichen die Alphas den Geigerzähler nicht mehr und das löst den Alarm aus. (Mit einem Blatt Papier können Alphas gestoppt werden, ebenso durch Rauch.)
Diese Dinger (die Rauchmelder) sind heute eine Rarität.

Where is the #MAGA #influencer telling followers to break open their smoke alarms and eat the Americium because that's the most #patriotic of all the elements? #AlphaEmitter #LifeHack #Americium

2015: Official Report: Nuclear Waste Accident Caused By Wrong Cat Litter

March 26, 2015
Geoff Brumfiel

"Workers at Los Alamos National Laboratory used organic cat litter to clean up #NuclearWaste. The litter triggered chemical reactions that later caused a drum to burst.

"A yearlong investigation by government scientists has concluded that a major accident at a nuclear waste dump was caused by the wrong brand of cat litter.

"The U.S. Department of Energy [#DOE] has released a 277-page report into an explosion that occurred on Feb. 14, 2014, at the Waste Isolation Pilot Plant [#WIPP] in #NewMexico.

"According to a summary of the report, the incident occurred when a single drum of nuclear waste, 68660, burst open.

"As NPR reported shortly after the accident, cat litter was the chief suspect. The highly absorbent material is great at soaking up liquid nuclear waste, and it has been used for years in cleanup activities at the nation's nuclear laboratories.

"Unfortunately, workers at Los Alamos National Laboratory, also in New Mexico, apparently switched from inorganic #ClayLitter to organic litter. According to the report, workers put the brand "Swheat Scoop" inside drum 68660.

"'Experiments showed that various combinations of nitrate salt, Swheat Scoop, nitric acid, and oxalate self-heat at temperatures below 100°C. Computer modeling of thermal runaway was consistent with the observed 70-day birth-to-breach of Drum 68660,' the summary of the report concluded.

"In other words, the litter caused the drum to burst after it arrived at the dump, releasing #radioactive #uranium, #plutonium and #americium throughout the underground facility.

"WIPP has come under intense scrutiny since the accident for what critics say was a lax culture of safety and oversight. But the Energy Department wants the dump to get back to work. It hopes to reopen it early next year."

My gamma spectrometer arrived yesterday. Unsurprisingly but thrilling, the smoke detector has Americium-241, which falls off to background levels (160 CPM) a half a meter away. Nothing else has shown gamma activity. I have some small element samples on order that should be interesting. I am curious whether it's worth it looking for thrift shop finds (uranium ceramics, radium watches) or if they are all routinely screened these days. #science #radioactivity #gamma #americium #uranium #RadiaCode

"The press have repeated a statement initially peddled by #TEPCO, that this contaminated water only includes #tritium. This is untrue, and tritium is not without its own risks. The water being discussed has been through the various filtration systems on site used to remove #radioactive #isotopes. Each system removes some of the radioactive elements in the water. ALPS is the last of these systems. It can remove much of the remaining contamination but not all of it, some radioactive contamination remains in this water.

"We [SimplyInfo] documented back in 2018 that this water contains other problematic radioactive elements including:

#Plutonium (238, 239, 240)
#Americium
#iodine129
#Technetium99
#Cobalt60
#Curium244
#Niobium94
#Europium (152, 154)
#Cesium137
#Strontium90
#Selenium79
#Nickel63
#Tin126 (aka: Sn-126)

"As of 2018 the stored post #ALPS water contained 200 billion becquerels of iodine 129, #ruthenium106, and technetium 99. As stored water increases, so does the total volume of contamination within that water.

"TEPCO and the Japanese government have tried to ease concerns by claiming the water will be diluted before it is dumped into the Pacific ocean. This is a meaningless step. The total amount of radioactive #contamination is still dumped into the ocean, you just dumped some additional water beside it at the same time."

🔋#Nature 📆 06 December 2022 #ESA is developing a #battery for #space missions that is powered by #nuclear waste. #Americium has a longer half-life than plutonium-238, which means it lasts #longer but packs less #power per gram. But because americium is more readily available, producing one watt of power #costs about one-fifth as much as it does using #plutonium. Tests will include monitoring the behaviour of components at high temperatures and under #impact — for example, during an #explosion 💥 on the #launchpad — to ensure that #radioactive ☢️ material would not leak https://www.nature.com/articles/d41586-022-04247-6
